If you buy a bone-in chicken breast, you can cut the tenderloin from the breast. It will be a narrow strip on one side of the breast between the breast meat and the bone.

Once you have removed the chicken tender, you can use the breast to make more chicken tenders. You can then slice the chicken breast meat up into similar-sized strips chicken breast meat. These should look like strips that are about 1 inch in width and 2-3 inches in length.
